Figure 2: In vitro selection of D2Cs.
From: Engineering interlocking DNA rings with weak physical interactions
(a) In vitro selection progress, as measured by the degree of catenation of LDNAii for each selection round. T1: time allowed for the hybridization between CDNAi and LDNAii. T2: time for DNA ligation. (b) dPAGE analysis of G1, G7 and G12 DNA pools.
